LeHardys Rapids

LeHardys Rapids is a rocky cascade on the Yellowstone River, about three miles north of Fishing Bridge. The river leaves Yellowstone Lake at Fishing Bridge and flows north here. This is a worthwhile pause on a Grand Loop drive for moving water and wildlife, but the rapids themselves are modest; they can feel underwhelming when nothing is active.

The signed roadside pullout is close to the river. A short boardwalk of about 400 feet reaches viewing platforms, and a longer riverbank walk continues beyond them. Uneven ground and stairs on the southern boardwalk mean this is not a step-free route; some wheelchair users may need assistance.

Yellowstone cutthroat trout once dominated the park's fish life. Heavy harvest in the 1960s led to tighter regulations that helped restore their numbers and age structure. The trout are an important food source for about 20 bird species and for mammals such as bears, river otters and mink. Interpretive information is available at the stop.

Paul LeHardy, a civilian topographer with the 1873 Jones Expedition, and fellow surveyor Cecil Gabbett tried to raft downriver toward the Lower Falls. Their raft capsized here, losing supplies; they continued on foot. The rapids carry LeHardy's name.

Some scientists consider these rapids the lake's geologic northern boundary, where Yellowstone Lake gives way to the river. The shifting rapids appear to influence how water drains from the lake. Think of that as a natural transition rather than a visible line in the water.
